  1. Good kit for the money - Posted by: Tyler (8/30/15)

    Installed the 4.5 inch suspension lift on a 04 Silverado in the garage. Start to finish only took me 3 1/2 hours. Super simple and good quality kit. Definitely the best bang for your buck. Highly recommend and looks great.

  4. Great lift kit. Does everything it's supposed to do. Great product. - Posted by: Daddy760 (5/23/14)

    I bought the 4.5 inch kit a year ago right when I bought my 03 Silverado and loved it, so now I just bought the 6 inch lift. They are great lift kits for the price and do the job just fine. I love it. On the 6 tho, my from end lowered about an inch . I need to find a way to fix that. But kit is highly recommended.. Good luck!!!
